When I set out to create a Micropub endpoint as flexible as the Kirby CMS itself, this turned out to be a rather complex task. The result, however, opens up opportunities that frankly surprised myself. Once the initial setup is done, publishing content is more flexible than ever.

Print stylesheets are one more example of the assumption-puncturing nature of the web: don’t assume that everyone will be reading your content on a screen. News articles, blog posts, recipes, lyrics …there are many situations where a well-considered print stylesheet can make all the difference to the overall experience. [...] So much as I might grit my teeth, QR codes and print stylesheets make for good bedfellows.
—Jeremy Keith I full-heartedly agree with Jeremy: print stylesheets are one more feature of universal website design, and they go together rather well with QR codes …no matter how ugly, abused and underused they are.
There luckily is an alternative to Google’s Chart API (whose shutdown had been announced for 2015 last time I checked; that’s three years in the past). In true Indieweb manner, QR codes can be self-generated locally using the open source PHP library PHP QR Code. Its latest version is eight years old, but it still works like a charm - check out the print preview of this post for a proof of concept.
Here’s the piece of code I use with above library to generate mine, before caching them on the server for output:
<?php
if ( isset( $_REQUEST['url'] ) && trim( $_REQUEST['url'] ) != '' ) {
include "qrlib.php";
// a writable location, where the temp PNG files are stored
$tempdir = dirname(__FILE__) . DIRECTORY_SEPARATOR . 'temp' . DIRECTORY_SEPARATOR;
if ( !file_exists( $tempdir ) )
mkdir( $tempdir );
// sanitize URL
$url = filter_var( urldecode( $_REQUEST['url'] ), FILTER_SANITIZE_URL );
// set error correction and code size
$errcorr = 'L'; // L (low, smallest QR code) -> M -> Q -> H (highest error correction, bigger QR code)
$size = 3; // width/height per "QR pixel" in pixels
// create QR code and store PNG in temp dir
$filename = $tempdir . md5( $url .'|' . $errcorr . '|' . $size ) . '.png';
QRcode::png( $url, $filename, $errcorr, $size, 2 );
// open PNG file in binary mode
$file = fopen( $filename, 'rb' );
// send the right headers
header( "Content-Type: image/png" );
header( "Content-Length: " . filesize($filename) );
// dump the picture
fpassthru( $file );
}
?>
Jeremy, maybe this allows you to prepare your talk free from any fear over a long-declared-dead Google API going away? The library even allows for SVG output, which might be neat for presentation slides - for web print styles I believe PNG to be the format with less inconsistencies.

NB. This is a two-years old post, only kept for archive purposes. The technology stack at either Twitter or Uberspace has since changed, and the described issue should no longer prevail - making this workaround obsolete. Ever since I migrated my website to HTTPS (and you should too!), I noticed

Along with the purchase of my Android phone came the convenience of a free and easy cloud back-up of my phone contacts and seamless synchronization with Google Calendar. However, I have since become more wary about whom I want to share my data with.
I decided that it was time to say goodbye to Google and try out ownCloud, the open source software package for hosting one’s own cloud services. […]

The archives reveal it was October 2005 when I started to use Delicious to collect my bookmarks, at a time where I had to use various computers daily.
Four years later, competitor Ma.gnolia lost all user data, marking the first occasion that I (along with a shaken community of their users) questioned the value of cloud services for storing personal data. Yet, both for lack of alternatives and for being lazy, I kept using Delicious - though making regular backups a habit.
Today, we live 2014 and it is time to move on; more specifically, time to reclaim ownership over my bookmarks and to host them myself. Naturally, having grown used to a cloud service, a suitable web-based replacement had to be found. […]
